Abstract

The invention discloses an ultrasonic power supply device with an array transducer. The ultrasonic power supply device with the array transducer comprises an upper personal computer (PC), a universal serial bus (USB), sixteen signal generation and power amplification modules, a phase-control signal bus and the array ultrasonic transducer. The upper PC is in communication connection with the sixteen signal generation and power amplification modules through the USB. The signal generation and power amplification modules are connected with the array ultrasonic transducer through the phase-control signal bus. A transducer array is driven through an array transducer ultrasonic power supply to achieve the functions of multi-frequency ultrasonic focusing, ultrasonic suspension and the like; the ultrasonic power supply device is suitable for construction of scientific research places and experiment platform; by the adoption of the modular design, a machine body and a circuit structure can be obtained easily, and the ultrasonic power supply device has broad application prospects and fills the blank of achieving application and study of multi-frequency ultrasonic focusing through the transducer array at present.

Description

technical field [0001] The invention belongs to the technical field of power supplies, and in particular relates to an array transducer ultrasonic power supply device. Background technique [0002] Ultrasonic generators are usually called ultrasonic generators and ultrasonic generators, and their function is to convert electrical energy into high-frequency AC signals that match the ultrasonic transducers. The principle of the ultrasonic power supply first generates a signal of a specific frequency by the signal generator, which can be a sinusoidal signal or a pulse signal, and the specific frequency is the working frequency of the transducer. [0003] At present, most of the research on ultrasonic power supplies at home and abroad focuses on the research of single transducers such as variable frequency, variable power, impedance matching, automatic frequency tracking, and intelligent control, and is applied to ultrasonic focusing, ultrasonic levitation, and "internal process...
